The Rottbach is an approximately 16 km long right tributary of the Lech in the districts of Landsberg am Lech and Weilheim-Schongau in Upper Bavaria .
Upper course
The Rottbach rises in a hilly moraine landscape near Puitl at an altitude of 745 m above sea level. NHN .
course
The Rottbach initially runs south past Streberg and then briefly forms the border between the districts of Landsberg am Lech and Weilheim-Schongau in the area of the Breiten Moos , before it completely enters the area of the Landsberg am Lech district.
A little later the Rottbach takes on the Lüßgraben from the left before it is dammed up to Lake Engelsrieder . This was created in 1510 at the instigation of the Wessobrunn abbot Kaspar Götz for fish farming , after a dam breach in 1905 the weir was rebuilt in 1921. There is a lido by the lake.
Shortly after leaving the Engelsrieder See, the Geiselmoosbach flows from the right, followed by the Kalterbach a little later.
After a bend to the northwest, the Rottbach passes the southern part of the village of Rott , before it increasingly cuts into a deep valley by a meandering river bed at Grubmühle . Finally, the Rottbach flows south of Apfeldorfhausen through a gorge that is about 70 m deep just before the confluence north of Rauhenlechsberg in the Lech.
Finally the Rottbach flows from the right into the Lech below the Lech barrage 9 - Apfeldorf at 635 m above sea level. NHN .
The 16.1 km long Rottbach flows about 110 meters below its origin and thus has an average bed gradient of almost 7 ‰.
